Re: WebOPAC, WAM and Blade Server

[Doug Kariel <dougk at athabascau dot ca>]

Hi

(Apologies to non-technical people) The general instructions we got was 
to give the new server a temporary IP and donmain name.  When the new 
server is replaced, the domain name can be the same as the old one as 
long as the DNS table has the correct IP address for the machine.   The 
technician will look after changing the names on the new box when it is 
installed and ready to cut over for production.  The machine has to go 
somewhere, so it is best that it be part of your campus range of IP 
addresses.

From a proxy perspective, it won't matter at all because the name gets 
resolved and it finds the machine.  When we put in our new server, we 
did exactly this and it worked fine. 

Hope this helps.
